tion, reference beingy had to the accompany-` ing drawings.

This invention relates to extension tables,

and has for its primary object .to provide a table wherein supplementary leaves are carried by the two relatively movable main table sections.

The invention has for another and more specific object lthe provision of two pairs of leaves carried by the respective sections of the table top, said leaves being of a length equal to one-half of the width of the top, and means for mounting the respective pairs of leaves whereby they may be readily eX tended when the top sections are separated to occupy the spaces vacated by the respective sections.

The invention has for a further object to provide two pairs of leaves arranged in opposed relation and slidably mounted upon the body of the table, means on the respective top sections for sliding the pairs of leaves in relatively opposite directions when said sections are moved toward or from each other, and means for elevating the table leaves whereby the same may be readily grasped and extended to their operative` positions.

The invention has for still another object to produce an extension table having selfcontained supplementary leaves whereby the extension of the table is greatly facilitated, and the manual labor incident thereto reduced to a minimum.

With the above and other objects in view, the invention consists in novel features of construction, combination, and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in Which- Figure 1 is a plan view showing the form of the relatively movable sections of the table top; Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1; Fig. 3 is a similar view showing one of the table leaves in its extended position; Fig. i is a longitudinal section taken on the line 4.-4 of Fig. 3; Fig. 5 is a detail longitudinal section taken on the line 5 5 of Fig. 2; Fig. 6 is a bottom plan view of one of the leaves and the hinged arm upon which the same is slidably mounted; Fig. 7 is a section taken on the line 7--7 of Fig. 6, and Fig. 8 is a detail fragmentary plan view, the table top sec tions being removed. Fig. 9 is a detail section taken on line 9 9 of Fig. 1.

Referring in detail to Vthe drawings, 5 designates the bottom wall of the table body which is of rectangular form in plan, and is mounted at its corners upon suitable supporting legs indicated at 6. Upon the marginal edges of the bottom 5 the upstanding side and end walls 7 of the table are mounted, said walls being secured by screws or other analogous fastening means to the bars or beams S which are secured upon the bottom 5 of the table. These walls are preferably dove-tail attheir ends in the supporting legs 6.

As shown in Fig. 1 of the drawings, the table top consists of two sections 9, each of which is of L-shape form, said sections having their longitudinally extending arms l0 extending. in opposite directions and provided with interfitting tongues and grooves on their inner longitudinal edges indicated at 11 for engagement when the table is in its closed or normal position. Each of said arms is of a width equal to one-half of the maXin mum width of the table top. rhese top sections 9 are slidably mounted for longitudinal movement on the upper edges of the side walls of the table, and each of the top sections has secured to its bottom face and contiguous to its longitudinal edges a cleat 12 which is provided upon its innerv face with a longitudinal rib 13. This rib is adapted to engage beneath a longitudinal shoulder 14 formed on the outer face of the side wall of the table positioned adjacent its upper edge. In order to relieve the side walls 11 of undue strain due to any tendency of the table top sections to shift transversely, each top section is further provided upon its bottom face inwardly of and in spaced relation to the cleats 12 with a slide bar 15. Each of these slide bars for a portion of its length is of rectangular form, and at its end extends through a recess formed in the top face of one of the table legs 6. A pin 16 projects downwardly from this latter end of the slide bar and limits the inner movement of the table section by engagement With said leg. The inner end portion of the slide bar 15 is reduced in thickness andi is slidably mounted upon the corresponding portion of one of the bars carried by the other section of the table top. These slide bars, as clearly shown in Figs. 2 and 3 of the drawings, are disposed for sliding engagement along the inner faces ofy the side Walls 7.

To the bottom 5 of the table contiguous to one ofthe longitudinal bars 8 a dove-tail guide bar 17 is secured.V This bar extendsv in parallel relation to the bar or beam 8 for top sections 9. The first named slide blockv 18is centrally provided in its upper edgeV With a notch or recess 23 to receive the lower end of an actuating element '24 which is fixed tothe under side of the other table top section. Thus, it will be apparenti that When the table top sections are moved with relation to each other upon the upper edges ofthe side =vvalls 7, the respective slide blocks 18 and 20 are correspondingly moved in l relatively opposite directions.

25 indicates then supplementary leaves. These -leaves are equal in length to the Width ofthe arms 10 of the table sectionsfQ.. The leaves 251are preferably arranged in pairs,l though it.' Will be understood that: a greater number may be provided if desired. Each ofthe leaves has securedto its bottom face and: along its oppositeA longitudinal edges, guides platesor rails 26, the inner edges of which are spaced from the surface of the leafand are slidably engaged in the grooves 28 formedinthe opposite edges of ai block 27. Thisblock is hinged as at` 29 upon the inner end of an armBO: To the outer end of each of' said arms a block 81 1s secured,

and said blocks of the respective pairs. ofy

ea vcarr inO arms a e l e L c lf yg rnngdasat32to the slide blocks 18 and 20,1espectively. It Will be noted that the arms 30 which are mounted upon the slide block 2O are longi-` tudinally curved to a slight extent; so that theiinner ends of the leavesl mounted-upon said arms. are normally supported at1 a higher elevation than the outer ends of'said leaves andare thus maintained in spaced relation to the other lower pair oftable leaves 25 in the sliding movement of the table top sections. In this manner liability of engagement of therespective pairs of leaves or the supporting arms With each other Would be precluded, and interference by the same with the sliding movement of the top sections thus obviate'd. end edges of one pair of table leaves is provided Witlianotchy or groove 38 to receive the tongue on the longitudinal edgeof one of the arms 10 of the table top, While the corresponding end edges of the other pair of: supplementaryY table leaves are vprovided f' With tonguesA 34k for engagement inthe' lonf git-udinali groove in the linner edgeV ofthe arm ofl the other top section. One of: the guideplates or rails/26 Which are secured to-thelatter pairfofa leaves 25 is extended beyond one end ofthe leaf for engagement with the block; 31, so aszto avoidthe possibility ofg mutilation of the tonguet.

As Wille be observed from. reference to F ig. 2 of,`thedravvings, the lovvermost pairV block 18 Will readily rideY over the same.

Therefore, as shown in Fig. 3 of the drawings, yvhen the table top section to Which the slide block operating member 24 is attached isA moved With respect tothe other top section, the lowerpair of table leaves and their supporting arms are, of course, alsomoved longitudinally over the bottom 5 of the table, and'when the arms engage with the lifting ribs 35, the inner ends of said arms are forced upwardly or elevated, thus also elevating the table leaves carried by said arms, T o the bottom face of each of the table leaves-,at vthe opposite endfthereto to that, providedwvith the tongue or groove, a cleat 36 is secured. These cleatsare of similar shape in cross section to the cleats 12`of the table top sections and are, adapted for engagement With the respective shoulderslt in a similar manner Wlienthesupplementary leaves are extended to their. opera-tive positions.

From the foregoing description taken in connection With they accompanying draw.- ingsthe construction, manner ofuse, and

several advantages of my improved eXten-y sibletable Will beclearly and fully understood. TWhen the table top sections arelin their-closednormal positions, the respective pairs'. of supplementary leaves 25 occupy the relative positions With respect to each other lic ' evo between the top of the table and the bottom 5 as shown in dotted lines in Fig. 1. The two top sections 9 are extended longitudinally upon each other until the end edges 0f their arms 10 are in alinement. The respective pairs of leaves are normally located immediately beneath the arms 10 and moved with said sections. When the sections have been extended las above stated, the lowermost pair of table leaves being elevated by the lifting ribs 35, as hereinbefore explained, the inner ends of one pair of table leaves are pulled outwardly upon the blocks 27 which are hinged to the arms 30 so that said leaves will occupy the space which has been vacated by the arm 10 of the other table top section.

The other pair of supplementary leaves 25 are extended in an opposite direction with respect to the first pair of leaves into the space formerly occupied by the other of the arms 10. The cleats 12 and 36 on said arms are, of course, engaged with the longitudinal shoulders 14 on the respective side walls of the table, and the tongues or grooves on the end edges of said leaves are engaged with the groove or tongue of the table top arms 10 as the case may be. When the leaves are thus arranged, the arms 30 will beangularly disposed between the inner ends of the leaves and the respective slide blocks 18 and 20.

In this manner it will be seen that I have produced a simply constructed, as well as highly convenient and serviceable extension table, wherein a large number of supplementary table leaves are at all times containedwithin the table itselfl so that the operator is relieved of the excessive labor incident to the bodily removal or insertion of the leaves incident to the use of the ordinary table of this character.l l/Vhen the table sections are moved inwardly toward each other to their closed positions, the pins 16 engaging the upper ends of the table legs preclude all possibility of injury to the abut-y ting edges of the table top sections by forcible engagement of the same with each other. My improved table is also very durable in its construction, and may be produced at small manufacturing cost.

While I have above described the preferred form, construction, and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, andI therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied Within the spirit and scope of the invention as claimed.
